Definitions

  • Silicone although a very effective release agent, can cause defects in the rubber article. If during the vulcanization process, the rubber flows and folds over on itself, then the silicone will prevent the surfaces from adhering. For this reason, it would be desirable if silicone could be eliminated from the inside green tire paints.
  • the first necessary ingredient of the novel inside green tire paint is a rubber latex.
  • the rubber latex serves the purpose of reducing flaking of the paint from the cured and uncured tire.
  • the rubber latex acts as a binder which keeps the paint on the tire. Paint flaking can be a serious problem especially when the paint comes off the inside of the tire as it is being removed from the mold. The paint will fall into the tire mold and cause the mold to become dirty and also cause defects in the subsequent cured tire.
  • the type of rubber latex used can vary, however, natural rubber later is preferred with styrenebutadiene latex next preferred. Other types of rubber latex or a blend of more than one latex may be used.
  • the second necessary ingredient of the inside green tire paint of this invention is a wax dispersion.
  • silicone serves the function of allowing the bladder to slip on the surface of the tire as the tire is being shaped into the mold.
  • the wax dispersion serves a similar function to silicone. Wax, being more compatible with rubber than silicone, does not interfere with liner splice adhesion as does silicone.
  • wax dispersion The type and amounts of wax used in the wax dispersion are critical in this invention to making a satisfactory inside green tire paint. For example, if a very low melting wax were to be used, then the wax would melt as soon as the hot bladder contacts the inside surface of the tire. The melted wax could form puddles and smear thereby resulting in a defective tire. In the opposite situation, where the wax has too high a melting point, there would not be enough softening of wax as the hot bladder touches the tire and therefore the bladder would not slip on the inside surface of the tire.
  • the carnauba portion of the wax should be more than about 6 to less than about 50 percent by weight of the total weight of wax.
  • the carnauba wax will constitute from 20 to 30 percent of the total amount of wax.
  • the remainder of the wax portion is paraffin.
  • the melting point of paraffin wax used is dependent upon the type and size of tire to be coated and the level of carnauba wax used. A particularly desirable ratio has been found to be 25 carnauba, 25 paraffin (72° C.), and 50 paraffin (50 C.).
  • the ratio of and type of waxes used will also vary depending upon the type of vulcanizing equipment used. For example, when using a vulcanizing press which does not have a center post such as an autoform, more slip is required and therefore a large proportion of paraffin wax should be used. Whereas, a Bag-O-Matic type vulcanizing press requires less slippage between bladder and tire and therefore less paraffin can be used and more carnauba.
  • the wax dispersion contains water, a dispersing system such as soap, and a surfactant.
  • a dispersing system such as soap
  • a surfactant such as soap, it has been found that the soap can be made in situ by using a fatty acid such as oleic, stearic, or lauric acid and the like and an amine such as monoethanolamine.
  • the third necessary ingredient of the novel inside green tire paint is a pigment capable of functioning as an air bleeding agent.
  • pigments which are capable of functioning as air bleeding agents are mica, talc, carbon black, and the like. Mica has been found to be an especially desirable pigment to use as an air bleeding agent.
  • the inside green tire paints of this invention also contain water as the carrier. Water is present in the rubber latex, wax dispersion and as free water added.
  • the prior art paints commonly use hydrocarbon solvents such as gasoline as the carrier. By using a water-based paint, harmful vapors are eliminated and precious natural resources are conserved.
  • the paints of this invention also contain a surfactant to aid in dispersing the ingredients in water.
  • the above paint was evaluated as an inside green tire paint by coating the inside of radial passenger and bias truck tires. Several thousand tires containing this paint were vulcanized and no paint related defects were observed. The paint was found to be very effective for slip and release between bladder and tire.
  • This Example is presented to show that a paint having 6% of the wax as carnauba wax will function satisfactory for passenger tires but will not function properly in tires having long vulcanization times such as truck tires.
  • the wax dispersion was made similar to that described in Example I except instead of 25 percent of the wax being carnauba, only 6 percent was carnauba. The remaining wax was evenly divided between 55° C. M.P. and 72° C. M.P. paraffin wax.
  • the paints of this invention also have an important feature which is not present in the prior art paints. Since the paints are water based, they can be washed off the inside surface of the tire by steam cleaning. This is an important advantage since often the inside surface of a tire will need to be cleaned in order to adhere a repair patch.
